get_my_market_listings does not collect buy_orders

[Aarab228]

There is an account that is doing well and its json tree looks like this

And there's an account that has a json that looks like this

At the same time, buy_orders are the same on one and the other account. I tried to look at the market.py code in order to understand how it works in principle, but I failed. Also the documentation doesn't say anything about it and I don't know what to do. I often have such massive steam accounts, so I'm worried that I won't get buy_orders always. Is there an option to solve this issue?
